Speed up the key oxygen-oxygen bond-formation (O=O) step in water oxidation

Two new molecular catalysts of water oxidation have been synthesized by a team of brilliant scientists from the U.S. Department of Energy’s Brookhaven National Laboratory. These new molecular catalysts – complexes of ruthenium which are surrounded by the binding molecules, and they contain phosphonate groups. Their functions are to accelerate the formation of the O=O bond, which is the slowest step of oxidation of water.

More evidence of RNA has been offered by the chemists as the origin of life

It is believed that the origin of life has started with the prebiotic molecules which usually react along the unidentified paths to produce nucleosides which are a key molecule. A team of chemists has shown how guanine and adenine can be synthesized easily in a reasonable yield. They have offered some of the more evidence that RNA is the origin of life on the Earth.

The blood clots are detected by new technology with simple test at home

The patients who suffer from kidney disease, congestive heart failure, atrial fibrillation, hypertension, cardiovascular disease and the patients who have a risk of blood clotting, are especially vulnerable when the levels of blood-thinning medication get very weak or strong. A blood screening device for these patients has been developed by the scientists.

A catalyst has been designed by the chemists which provides with a huge shortcut for how an abundant, simple molecule is turned into a much more value-added and complex molecule by the chemists. Another step has been taken by the chemists to use the carbon-hydrogen bonds (C-H) for creating new molecules.

Targeted orphaned domain may lead to drug therapies

The intercellular domain (ICD) has been focused by Jansen’s lab which is diverse. The researches may even result in some new therapies of the drug without the effects which were not desired, by targeting this domain. The intercellular domain was considered as extremely disordered a few years ago. However, the ordered assembly of five ICDs has been shown by this research.

Cancer detection can be improved by new device

A new method which has been developed by UBC to isolate the cancer cells which escaped from a tumour could soon pave the way for improved treatment and diagnosis. A simple device is involved in the simple process which squeezes the cells in a blood sample through tiny funnels. However, this research is mainly focusing on microfluidics, the flow of liquids through the channels which are even smaller than a human hair

An enzyme enigma discovered in the abyss

The secret of the ‘Mona Lisa of chemical reactions has been uncovered by the scientists of the Universities of Bristol and Newcastle. This has been done in a bacterium which lives at the bottom of the Pacific Ocean. The scientists are hoping that this discovery can result in developing new antibiotics and other medical treatments.

Explore the mystery how enzymes work via simulations

Enzymes play a very significant role in most of the biological processes for controlling energy transduction. Hence, keeping these things in mind the scientists are trying to understand the origin of the catalytic power of the enzymes. This study has reviewed several proposals which are governing the catalytic efficiency of enzymes.

New way of growing crystals discovered

The scientists have discovered a new way of growing the crystals at the University of Bristol. Polymorphism in the polyaromatic hydrocarbon coronene has successfully been controlled by the scientists by producing a crystal structure which had never been observed before. This has been achieved by them by simply growing the catalysts in strong magnetic fields.

Exploring the landscape of cell receptors

Professor Scott Prosser and post-doc Libin Ye have found out the reason how caffeine works to provide that extra boost when needed. The class of cell signaling receptors which are also called as GPCRs are responsible for the basic processes such as chemical signaling in the brain, smell, taste, and vision. The GPCRs are often likened as the molecular switches which are blocked by the drugs.

Silk protein used to air-dry blood samples for remote testing

A new way to store blood the samples which are taken at remote locations has been developed by the team of researchers at Tufts University. That team of researchers used a silk protein to stabilize the blood samples without any need of cooling them.
